This paper is concerned with the distribution of manganese and the growth process of the manganese micro-particle in the Suruga Bay. The results obtained are as follows; (1) The manganese contents in the sea water are 2-4μg Mn/l, 4-17μg Mn/l and 1-4μg Mn/l in the surface, intermediate and deep layer respectively. (2) Three major classifications of the microparticle seem to be possible, namely, needle like micro-particle (10-30μ), sea urchin like microparticle (20-400μ) and granular micro-particle (10-1000μ). (3) The intimate relation seems to be exist between the dissolved oxygen and the content of manganese. The former decreases sharply in the intermediate layer where the latter increases evidently. This fact indicates the geochemical condition necessary for the genesis of manganese micro-particle.
